Lithium Ion Battery

Battery Management System

Battery Management System

A Battery Management System (BMS) is an electronic component of the battery and can be considered as the brain of the system that manages the charge and discharge processes of a pack. The primary job of a BMS is to protect the battery (by preventing operation of any cell outside its safe operating area).
